Fast pls solve this question correctly in 5 min pls I will give u like for sure Nidi 10.2 Calculus #13&14
11-16 Find dy/dx and d²y/dx². For which values of t is the
curve concave upward?
11. x = 1² + 1, y = 1² + t 12. x = t³ + 1, y = 1² - t
13. x = e', y = te'
15. x = 2 sin t, y = 3 cost,
16. x = cos 2t, y = cos t, 0<t< T
14. x = ² + 1,
0 < t < 2π
y = e' - 1
